Gant says he's looking forward to returning to the private sector at the end of his term, which runs through the end of 2014.

Gant says he has accomplished his goals, including creating an online corporate filing system and putting more open records online, increasing transparency in campaign finance and increasing access to the voting booth. He says his successor will inherit a government agency "that is at the forefront of technology."

Gant, a Republican, has faced criticism from both Democrats and Republicans since taking office in 2011. He says he's "far from perfect" but that he's always tried to do his best "and serve the people of South Dakota well."
